Background Renal transplantation is the definitive treatment for patients with end-stage renal disease (ESRD). It is associated with better quality of life and patient survival. Nevertheless, these benefits come with rising concerns about weight gain and metabolic abnormalities, which adversely impact transplant outcomes. Objective The objective of this study is to estimate the incidence of weight gain in the first year post-renal transplant in addition to the assessment of potential risk factors and the resulting outcome of the graft. Methods We conducted a single-center retrospective cohort study of all 295 patients who underwent kidney transplantation at King Abdulaziz Medical City (KAMC) between January 2016 and December 2019. Clinical and laboratory variables were collected from electronic records. Continuous variables were reported as mean ± standard deviation. Comparison between groups was assessed by unpaired t-test or Mann-Whitney U test while follow-up data were compared using paired t-test and repeated measures ANOVA. Association between the potential risk factors and the weight gain was assessed by means of binary logistic regression analysis. Results Significant weight gain was observed in 161 (54.6%) patients. Females were 119 (40.30%) of the cohort. The mean age was 45.3±15.1 years. The prevalence of diabetes was 234 (79.6%), while hypertensives constituted 77 (26.3%). The comparison between patients who gained weight significantly and patients with stable weight showed a numerical higher prevalence of female gender in patients who had more weight gain (44.1% vs. 35.8%), higher diabetes, higher rate of a living donor, and statistically significant lower dialysis duration before transplant. Other clinical and laboratory variables were comparable between the two groups. Conclusion Our study showed a high incidence of clinically significant weight gain among patients post-renal transplantation. Patients with lower dialysis duration, a living kidney donor and those who are obese at baseline were at higher risk of gaining weight. Patients who underwent kidney transplantation should be monitored closely for weight gain and further studies are needed to determine the risk factors and appropriate interventions.
Parvovirus B19 (PB19) is a single-stranded DNA virus that belongs to the Erythrovirus genus within the Parvoviridae family. Clinical presentations associated with PB19 infection vary greatly, depending on the infected individual’s age and hematologic and immunologic status. The limited data available regarding consensus on screening algorithms and indications in donors and recipients prior to kidney transplantation makes diagnosis and management challenging. We presented 3 cases of pure red cell aplasia due to parvovirus B19 after kidney transplant. These patients were diagnosed with severe normocytic, normochromic anemia (hemoglobin below 60 g/L) in the 1st 6 months posttransplant. A complete anemia work-up revealed low reticulocyte count and was otherwise inconclusive. All patients were diagnosed with pure red cell aplasia due to parvovirus B19. Two patients improved after receiving intravenous immunoglobulin 2 gm/kg given over 4 doses. Unfortunately, they relapse after few weeks and required additional doses of intravenous immunoglobulin in conjugation with reduction of their immunosuppressive medication. The third patient improved after holding mycophenolate mofetil (MMF) and did not require intravenous immunoglobulin. Whereas PB19 infection is typically self-limiting and associated with positive IgM serology in immunocompetent hosts, these cases highlight the importance of considering PB19 infection in the differential diagnosis of persistent anemia in immunocompromised patients and the challenges in confirming the diagnosis. Intravenous immunoglobulin (IVIG) can be an effective treatment in immunocompromised patients with primary or relapsed PB19 infection in conjunction with minimizing immunosuppressive medication. Further research and consideration are required to determine appropriate and targeted screening in donors and recipients in the peritransplantation period.
Introduction Little is known about sudden unexplained death (SUD) in Saudi Arabia. Moreover, family screening and medical autopsy are not routinely performed due to perceived religious and cultural resistance. However, this has never been systematically examined. We sought to describe the prevalence and characteristics of family history of SUD and the attitude of family members toward medical autopsy and family screening. Methods This was a cross-sectional study utilizing an online survey distributed though social media platforms from August 15 to September 15, 2021. Participants’ characteristics, details about SUD cases, and the attitude toward medical autopsy and family screening were collected. Multivariable logistic regression was used to identify independent predictors of negative attitude toward medical autopsy. Results A total of 11374 were included in the final analysis after excluding children. The prevalence of FHx of at least one first degree relative (FDR) with SUD was found to be 9.4% [95% CI (8.9% - 10%)]. Among participants with any FHx of SUD, 1346/3489 (38.6%) had ≥ 2 family members affected. Only 183 participants with a FHx of SUD visited a physician for the purpose of family screening (183/3489, 5.3%). The total number of SUD cases reported was 5474. Of those, 22% were 35-year-old or younger. Only 22% of participants (2458/11374) had a negative attitude towards medical autopsy, and the most common reason was the perceived lack of benefit. Older age (> 35 years), family history of SUD, female gender, and lack of knowledge about the yield of medical autopsy were associated with negative attitude in the adjusted analysis. Conclusion SUD occurred at young age and affected multiple family members in a significant proportion of families. Despite that, family screening was seldom performed. There is an urgent need to improve the care of SUD by incorporating medical autopsy and developing clinical pathways to screen family members.
